The TPS92691PWP is an integrated power management integrated circuit (PMIC) containing an efficient current-mode, step-up LED driver and a linear regulator (LDO). It is designed to support applications that require accurate LED current with both a high-side and a low-side current sink. It can drive up to 10 LEDs in series with adjustable current at constant brightness or be used to provide constant current for multiple high brightness LEDs (HB-LEDs).

The TPS92691PWP LED driver has an adjustable operating current of up to 30mA and an adjustable LED current of up to 60mA enabling it to meet most LED applications. The LED current of the LED driver can be set via an external resistor and it has excellent efficiency and low noise even at low power levels. The device also has built-in short-circuit protection and an open-drain logic output for under-voltage lockout (UVLO) protection.

The linear regulator on the TPS92691PWP provides a high-efficiency, low-noise, and low-ripple voltage regulation with a maximum output current of 75mA. The device has a wide input voltage range and can be used to regulate either positive or negative voltage supplies. An internal leading-edge low-side switch (LES) is also included to protect the system circuitry in the event of an overload or an over-temperature condition.

The TPS92691PWP\'s wide operating range enables it to meet the needs of multiple applications including automotive ICE engines, automotive interior and exterior lighting and general lighting applications. Its small footprint and low profile make it ideally suited for space-constrained applications and its high efficiency (up to 95%) and low noise make it a great choice for energy-sensitive and noise-sensitive applications. The TPS92691PWP is also rated for -40°C to +85°C operation with junction temperature sensing for improved system protection.

In summary, the TPS92691PWP is ideal for applications requiring efficient and accurate LED current control with both a high-side and a low-side current sink. The device\'s small footprint, high efficiency, and low noise make it a great choice for space-constrained, energy-sensitive, and noise-sensitive applications. Its wide operating range and built-in protection features make it suitable for a variety of applications including automotive ICE engines, automotive interior and exterior lighting and general lighting.
